Can it remove hair and a scar in the same spot?

The Aerolase Neo would be a great option for hypertrophic scar treatment, especially scars with increased pigment (red in this photo). The Aerolase Neo is approved for treatment on all skin types and for scars such as the one noted in your photo, a series of treatments would be necessary.

No, the Aerolase laser is so gentle that it does not affect fillers in the face. If one is highly concerned, please do the laser treatment first and then follow it with a filler injection.  Sincerely,  Dr. Andrew K. Choi

Hello, without knowing how your skin responds to either one.  It is always safe to do the treatments two weeks apart from each other.  I would also consult with the Physician or Nurse that would be performing the treatments. Best Wishes to you,
